" This invention relates tocard perforating machines or the like.

to make holes in cards at predetermined points thereby making the card a record card, and these holes are afterwards interpreted in'what is known as a tabulatingmachine through 'whichthecards are afterwards passed.

It is common practice to divide up the cards into zones involving sometimes six 'c'olumns for each zone, and it is common'practice also to allot zones for credit and debit accounts entered on the card bythe per'forating, machine. 7 F

If the card is of an account in which the credit means an addition in. the tabulator, then the zone in which the debit entries are made means that the tabulator has got to subtract. p

Tabulating machines employ adding mechanism incorporating what isknown asend to end transfer which .permits'the.subtrac used in the perforating machine, that is to say, cards which have an equal margin and iniwhich the lines numbered 0 to 9 are equally spaced from theedge.

Bythe use of such cards .it is possible to eliminate the act of the operator of inverting thecards, thereby eliminating the chances of human error in this operation.

According to the. present, invention apparatus for producing record cards or the like for use in operating statistical machines com prises means for simultaneously making on a cardy'direct and complementary records of an amount, said means also permitting a direct-recordonly of the amount to be made.

Vi here the records are made by making per vided with means,1whereby on the actuation of a single. punch key, holes are punched simultaneously in the card in theilines corresponding to numbers complementary to' wforations in the card, agpunch perforating I machine, for this purpose is conveniently pro- I Card perforating machines are employed one another. Thus if the key 2isdepressed' it for operating the punch, holes will be made both in-the 2 and in the 7 line; 1

Preferably, complementary mechanism is incorporated so that as the carriage is traversing over the card normal setting may be eifected in several zones and when a pre- 7 determined zone for example the credit zone is approached the complementary mechanism isintroduced preferably automatically" so as toiproduce a complementary'setting in another zone for example the debit zone.

Alternatively, the complementary mechanism m y be s t by hand for use as and when "required; 1 In the application of the invention to a punch for perforating mach-ines as described No. 419,974 now patent No. 1,858,17 4 filed on the-10th January, 1930"whether ornot .the carriage return mechanism is employed, the carriage may be constructed so as topunch either in the normal manner or so as to punch the complementary holes. i

* In the construction illustrated in the drawings the carriage 1 is provided with two sets .2 anda set' of complementary plungers' o.

of setting plungers, a set of normal plungers i If there are ten set bars inra column there will be ten of eachtype of plunger disposed. in a row across the field of set bars .soas to be capable ofbeing brought into register with'any column of set bars. The normal plungers 2 are spaced apart from the complementary plungers bya distance a which is equal to the distance between the commencements of the two zones in which the plungers are respectively intended to oper ate, the normal plungers being disposed in front of or nearer the left-hand end of, the

carriage, than the complementary plungers. The carriage comprises a framework la which carries abell crank lever i for :each key plunger then depressing a set bar-c7 whichis in .turnlatched and afterwards co-operates punch Sto effect a with the corresponding recording operation.

In order.thatcomplementary punching may be carried out the bell crank 4 ofthe normalsetting plunger .2 islco'nnected by a v a bayonet'slot 9b which takes over arpin 20 onth e toe 2a of thenormal setting plunger 2 link 9 to a stirrup -10 pivoted at 10a, so as to constitute :a rocking member, one arm of this stirrup being connected to a normal plunger while the other arm is connected :to the corresponding complementary plunger. Thusif one'arm of the stirrup is connec'ted-to anormal plunger which co-acts with the set bar corresponding to the numeral 3 the other arm will be connected to the complementary plunger which co-acts with the set bar correspondingto the numeral '6. c

Thereby, when the stirrup is rocked consequent upon the depression of a corresponding key the rocking motion; is translated into a downward movement of the plunger 3 by pin 11 engaging over the-knife edge3b; p i p r To control the position of the complementary plungers 3 automatically so that they are in the inoperative or the operative position, the complementary 'plungers are each carried for vertical displacement on a guide constituted by a rod 12, the complementary plunger being slotted at 30 for riding there Over. c 1 z The rod 12 on which thecomplementary plungers 3 are guided is itself carried in frame 13 pivoted on the carriage. l

the link carrying the roller being'pivoted to the carriage-at 18a. i I Y The machine is provided with a cam path which constrains the movement of the roller l9 as the carriage traverses the fieldof set bars 7, Norm-ally, thi's is a horizontal path ,sothattheframe 13 on which the complementary plungers3 are carried is not affected. To'obt-ainautomatically action from the complementary plungers 3 a guideway 20 slotted at 21is provided on the side of the machine for the passage of the roller 19 (Fig. and associated with this guideway is a'manually operable member in the form of two parallel 'bar'm'embers 22, 23, connected-by bridge pieces 24 which clear the operating roller 19 before referred to as it travelsin the constraining slot 21 (see Fig. 3). 1

To the upper bar 22 is pivotally attached a latch member 25 provided with two notches a, 25?; which provide two longitudinal po- 7 sitions for the bars by engagement over a fixed pin 26 on the machine frame. The bottom bar 23 of the pair is, provided with cam slots 23a which ride over pins 27 fixed J bottom of the slot both bars are in the highest positionland this causes an extended cam face28 on the bottom bar 23 to overlap the constraining slot 21 forthe'roller 19, so that the rolleris lifted up from its normal path thereby causing the operation of the frame 13 carrying thecomplementary plungers 3.

1 In such a construction it is convenient to makethe' normal slot 21 of wider form at the area 'where the extended cam face 28 ofthe mentary to the extended cam face 28 on the bottom bar 23 as shown in Fig. 3, so that the roller 19 is positively guided throughout its path by riding in a slot from end to end wherein the normal path changes where the extended cam face 28 overlaps. i

It will be understood; that the length of the cam 28 cannot be longer than the distance as between the commencements of the two zones in which the normal and complementary plungers respectively operate; otherwise the complementary plu-ngers 3 will release the set bars 7 set up by the plungers 2, as the carriage passes to the. next zone. Further,

it will also be clear that it is not possible to set up other information in the. zone meant for complementary number punching.

By the present invention a perforating machine isoperable to directly make the records necessary to cause a subtraction to be effected-in the adding mechanism of a tabulator without any special manipulation of the cards. Moreover, the fact that the cards can be used the right side up when a subtraction is being made in the tabulator permits the use of other perforations in the card for special-operations in the tabulator, which ofcourse, cannot be employed when the card. isreversed unless such reversed card was perforated suitably so as to-cause the, simultaneous operation inthe tabulator, a practice not employed because of the relativeirregnlariies of the perforationsso formed due to the fact that in the inverted-positionopposite edges of the card would be used for registering purposes; 7

Cards perforated by means of a machine constructedin accordance with the invention are subsequently passed through-a tabulater which records the amounts punched on the cards, there being one card for each item inanaccount. I

Conveniently, the bottom part 41a of the L isslotted at 416 to ride over a pin 42 carried bythe carriage frame. 1 .7
